Abstract

In the arrangement of the windings on the compartmented coil former (21) on the core (20) of a switched-mode power supply transformer (5), the secondary winding (17) for the audio output stage (15) is to be mounted in such a manner that the power dissipation caused by different power outputs of the audio output stage is reduced. For this purpose, the secondary winding (17) for the audio output stage (15) is arranged directly above the air gap (22) of the transformer core (20). Particularly for switched-mode power supply transformers in a television receiver. <IMAGE>
